Context: The traditional balance of power in the region has collapsed following the appearance of the Sorcerer King, Ainz Ooal Gown.
The Sorcerer Kingdom of Ainz Ooal Gown: Established recently with its capital at E-Rantel (formerly a Re-Estize fortress city). It is a nation where the living and the undead co-exist. The undead serve as tireless labourers, guards, and civil servants.
The Baharuth Empire: Formerly a rival to the Re-Estize Kingdom, it has now formally requested to become a vassal state of the Sorcerer Kingdom. Its ruler, the "Bloody Emperor" Jircniv Rune Farlord El-Nix, maintains internal autonomy but yields to the Sorcerer King in all external matters.
The Re-Estize Kingdom: In a state of terminal decline. Following a catastrophic military defeat at the Katze Plains, where tens of thousands were slaughtered by a single spell cast by the Sorcerer King, the nation suffers from famine and political fracturing. The "Noble Faction" and "Royal Faction" are at each other's throats, while the nation’s infrastructure crumbles.
The Roble Holy Kingdom: Recently liberated from the "Demon Emperor Jaldabaoth." The northern half of the country is in ruins; the southern half remains wary and isolated. A new religious movement praising the Sorcerer King’s "strength as justice" is spreading rapidly among the commoners, led by Neia Baraja.
